WINDOW-SCREEN.

SPECIFICATION forming pan: of Letters Patent No. 339,691, dated April13. 1886.

Application filed February 2, 1886. Serial No. 100,642. (No model.)

To all whom, it may concern.-

Be it known that I, llIARGIOUS O. RADWAY, a citizen of the UnitedStates, residing at Ripon, in the county of Fond du Lac and State ofYVisconsin, have inventeda new and useful Improvementin'Window-Screens,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in window-screens, and has for itsobject the provision of an article of the class named adapted to fitwindows of difi'erent widths, as also those wherein one or both of thesides of the windowframe have been by accident displaced from its ortheir normal vertical position, to be quickly placed in proper positionin the window-opening, securely held therein, and readily re movedtherefrom, and also to combine cheapness of manufacture, durability ofstructure, and neatness of appearance.

To these ends the invention consists in the construct-ion, arrangement,and combination of the several parts for service, substantially ashereinafter described, and specifically pointed out in the claims.

In the drawings, Figure 1 represents a side elevation of a window-screenembodying iny improvements. Fig. 2 is a top plan view thereof. Fig. 3represents detached detail views of parts of the improvement.

Referring to the drawings, in which similar letters of reference denotesimilar parts, A designates the frame of the screen, consisting of thetop and bottom rails, a a, and end rails, a".

b designates a sheet of the ordinary screen wire placed upon one side ofthe frame A, and secured thereto by strips b of wood.

G designates springrails that operate at each end of the frame A, uponthe surface opposite to that whereon is secured the wire cloth Z).

D designates the springs to which the rails C are connected, and bywhich said rails are operated. Said springs consist in straight portions(1, connected at their outer ends with the rails G, that move freely inlongitudinal direction in loops or staples cl, affixed to the top andbottom rails, a e, at the ends thereof,

as shown, laterally-curved U-shaped spring portions (2", joined by aloop, (i with the parts (I, and straight parts (1*, the outer ends,

d of which are bent inwardly, for the purpose of holding, in connectionwith staples d, the spring firmly to the surface of the rail. The parts(1 d are in alignment, as shown.

I provide each corner of the frame with a spring, D, the U-shapedportion d of each of which projects toward the outer ed go of the topand bottom rail, respectively, as shown, and extend thepart d of saidspring to and into the rails O at points (2 near the ends thereof,whereby great freedom of movement is imparted to said rails in lateraldirection, and whereby either the upper or lower end of the rail 0 maybe pressed outwardly to a greater distance than its opposite end, asshown by dotted lines in Fig. l. I deem this feature of importance, asthereby the frame or screen may be applied to windows having one or bothof the sides of the window-frame out of position, and at angles otherthan right angles with the window-sill.

It will be observed that the rails G are held solely by the rods (1, andthat said rails move freely upon the face of the frame.

The operation of my improvement will be readily understood withoutfurther description.

In order to define the nature and scope of my invention, 1 would statethat hcretoioreit has been proposed to provide an adjustablewindow-screen consistingof an ordinary frame having guide-staples at itscorners, laterallymovable strips for bearing against the windowframe,and arranged at the side of ,the end portions of the screen-frame andprojecting beyond the same, headed guide-pins secured to the strips andworking in the staples at the corners of the frame, and \l-shapedsprings formed from a single piece of wire, and secured at their apicesto the middle of the screen-frame and at their extremities to themovable strips.

In my improved device I employ the screenframe and the laterally-movablestrips, and the strips are carried and pressed by springs D, of peculiarform, that are secured at each corner of the frame and I thus dispensewith the use of separate guide pins and staples, as has been heretoforecommon. The springs are bent from a single piece of wire, and comprisetwo straight arms, that are connected by an intermediate curved orbow-shaped section, strips, and thearm d attached to the screenone ofthe arms being secured to the screenframe and the other arm to themovable strips. The arm 61 of each spring that connects with the stripsis movable longitudinally and guided in staples that are secured to theframe, and by means of the curved section of the spring the arms d andthe strips are normally forced laterally of the screen-frame, so as tohold the same very securely in the windowframe. I thus provide aremovable and adjustable screen that can be easily and readily adjusted,and which can be i'nanufactured for a trifling sum.

I claim- 1. The combination of a screen-frame, the movablepressure-strips independent of the frame, and the springs carrying thestrips, and comprising the horizontal arms (I (2, connected by anintermediate curved section, the arm d of each spring being secured tothe arm (1* secured to the screen-frame, substan-.

tially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
